Amazon is offering $8.62 off any purchase of $50 or more — Today Only [Expired]

Amazon is celebrating their #1 corporation ranking by giving all customers $8.62 off a $50 purchase. Simply add $50 or more worth of items that are sold and shipped by Amazon to your cart and enter promo code BIGTHANKS to receive the discount. If you don’t have anything you need to buy, I suggest picking up a $50 gift card to somewhere you frequently shop, like one of the following:

Also, this offer ONLY applies to products that are SOLD and SHIPPED by Amazon both, not just items shipped by Amazon as the post indicates.

I tried to use the discount code with a $100 plus item that was sold by a 3rd party seller but was going to be fulfilled by Amazon as an Amazon Prime purchase. And the Amazon system wouldn’t accept the use of the discount code for that kind of purchase.

And when I checked the actual T&Cs for the deal, I found the following language:

“Terms & Conditions:

Today only, get $8.62 off your purchase of $50 or more when you apply promo code BIGTHANKS at checkout. (Actually, we’ll round up from 8.627, so your discount will be $8.63.)

Offer expires at 11:59 p.m. (PT) 2/22/2017.
Offer only applies to products sold by Amazon.com.
Offer does not apply to digital content, video games, or Amazon Gift Cards.
Offer does not apply to orders placed through Alexa, Prime Now, Amazon Restaurants, or any mobile application other than the Amazon Shopping App.
Offer limited to one per customer and account.”

I could not get the code to work for me but to Amazon’s credit I emailed them and a rep immediately applied it to my order. (appropriate since the credit is for a customer service award)
The rep told me they were having “a lot” of technical difficulties concerning the code and apologized immensely!
